US EPA / January 2023 “ASHRAE recommends that homes receive 0.35 air changes per hour but not less than 15 cubic feet of air per minute (cfm) per person as the minimum ventilation rates in residential buildings in order to provide IAQ that is acceptable to human occupants and that minimizes adverse health effects.” Link […]
Chemical Engineering Journal / January, 2023 “The application of ultraviolet (UV) light in the food industry has held great promise for a long time. UVC light (200–280 nm) possesses excellent germicidal properties to inactivate a wide range of microbial pathogens (e.g., bacteria, fungi, yeasts, molds, and viruses).” Link to article.
Photochemistry and Photobiology / January, 2023 “The findings from this study support the long-term safety of long-term chronic exposure to far-UVC radiation, and therefore its potential suitability as a practical anti-microbial approach to reduce airborne viral and bacterial loads in occupied indoor settings.” Link to article.
Nature Scientific Reports / January, 2023 “By varying the lamp irradiance output, the number and positions of the lamps, the far-UVC irradiation can achieve a 3-log reduction for a dining duration of 5 min. Besides, the far-UVC lamp has a low damage risk to diners when achieving an effective inactivation rate.“ Link to article.
American Journal of Infection Control / November, 2022 “The present study clearly showed a bactericidal effect of far-UVC on ESBL-producing E. coli. We believe that irradiation with far-UVC may be potentially effective in preventing infection by ESBL-producing E. coli in health care settings.” Link to article.
Nature Scientific Reports / March, 2022 “For the first time, we show that Far-UVC deployed in a room-sized chamber effectively inactivates aerosolised Staphylococcus aureus. At a room ventilation rate of 3 air-changes-per-hour (ACH), with 5 filtered-sources the steady-state pathogen load was reduced by 98.4% providing an additional 184 equivalent air changes (eACH). “ Link to […]
GMS Hygiene and Infection Control / February, 2021 “Far-UVC – especially at a wavelength of 222 nm – is very effective against all pathogens…this is not a short-term solution for the current pandemic, but may be suitable for future technological approaches for decontamination in rooms in the presence of people or for antisepsis.” Link to […]
Journal of Hospital Infections / February, 2021 “The 222-nm UVC is able to inactivate a wide spectrum of microbial pathogens. In comparison with the conventional 254-nm UVC, the germicidal effect of 222-nm UVC to the fungal hyphae and spores is low, but the 222-nm UVC exhibits strong germicidal effect to the bacterial endospores.” Link to […]
Advances in Space Research / January, 2021 “The major advantage of far-UVC (222 nm) compared to traditional germicidal UVC (254 nm) is the potential for application throughout the spacecraft assembly process in the presence of humans without adverse health effects due to the limited penetration of far-UVC light into biological materials.” Link to article.
Nature Scientific Reports / June, 2020 “We previously demonstrated that 222-nm far-UVC light efficiently kills airborne influenza virus and we extend those studies to explore far-UVC efficacy against airborne human coronaviruses alpha HCoV-229E and beta HCoV-OC43.” Link to article.
